Definitions
- the present invention relates to an intaglio printing press, which can perform intaglio printing on both surfaces of a sheet in a single pass, and which also can perform intaglio printing on one surface of a sheet a plurality of times in a single pass.
- intaglio printing press for example, one as described in Japanese Patent Application Laid-open Publication No. 2001-096713 is known.
- this intaglio printing press performs intaglio printing on both surfaces of a sheet of paper
- intaglio printing is performed firstly on the back side of the sheet of paper.
- the sheet of paper is then left for several days, so that ink on the back side is dried.
- the sheet of paper is turned over, and is then fed to the intaglio printing press so that intaglio printing is performed on the top side of the sheet of paper again.
- the sheet of paper is left for another several days, so that ink on the top side is dried.

- the sheet 1 transported from the transfer cylinders 41 and 42 is transferred from the suction cylinder 43 to the convertible cylinder 44 to change the gripper thereof while the first and second surfaces of the sheet 1 are turned over.
- the sheet 1 is consequently transferred to the transfer cylinder 51 of the intaglio printing device 50 (refer to Japanese Examined Patent Publication No. Hei 6-041202 and Japanese Patent Application Laid-open Publication No. 2005-088450 regarding the detailed turn-over operation).

Figs. 1 ,4 and5 , aninker frame 151 is fitted into amain body frame 101 of an intaglio printing press, in a portion in a vicinity of thepattern roller 55d and theinking device 56d of theintaglio printing device 50. Theinker frame 151 movably supports thepattern roller 55d and theinking device 56d. Theinker frame 151 is fitted thereinto in a manner that theinker frame 151 moves along the horizontal direction perpendicular to the transporting direction of thesheets 1 with respect to themain body frame 101, that is, along the axial direction of thepattern roller 55d. -
Guide rails 154, each having a substantially H-shaped cross section and serving as an engaging portion, are attached respectively to one side and the other side (the right and left sides inFig. 4 ) of theinker frame 151 in the horizontal direction along the transporting direction of thesheets 1. The guide rails 154 are attached thereto also in a manner that the longitudinal direction of eachguide rail 154 is aligned with the horizontal direction perpendicular to the transporting direction of thesheets 1, that is, with the axial direction of thepattern roller 55d. Each of the guide rails 154 extends so as to project to the outside of theinker frame 151 on the other side thereof (the right side inFig. 5 ) in the horizontal direction perpendicular to the transporting direction of thesheets 1 for a length equal to or more than the length of theinker frame 151 in the horizontal direction. Each of theguide rails 154 can be deflected at a certain degree in the up-and-down direction. -
Guide members 155, each having a substantially C-shaped cross section, are attached to themain body frame 101 respectively in vicinities of the corresponding guide rails 154. Theguide members 155 serve as engaged portions, and are engaged respectively with theguide rails 154 in a manner that theguide members 155 hold therespective guide rails 154 so as to allow theguide rails 154 to slide in the longitudinal direction. Ahandle 156 is attached to one side (the left side inFig. 5 ) of theinker frame 151 in the horizontal direction perpendicular to the transporting direction of thesheets 1. - A pair of
wheels 152 are attached to that one side (the left side inFig. 5 ) of theinker frame 151 in the horizontal direction perpendicular to the transporting direction of thesheets 1 withbrackets 153 in a manner that thewheels 152 are spaced apart at a predetermined distance from afloor 100 where the intaglio printing press is placed.

Once theinker frame 151 is positioned at the outside of the printing press, theguide rails 154 are deflected due to the weight of theinker frame 151, so that thewheels 152 are brought into contact with thefloor 100. As a result, theinker frame 151 is movably supported on thefloor 100 with thewheels 152 and thebrackets 153. Accordingly, it is possible to pull out theinker frame 151 in the horizontal direction perpendicular to the transporting direction of thesheet 1 while thewheels 152 are caused to roll with respect to thefloor 100, thus bringing out thepattern roller 55d and theinking device 56d to the outside of themain body frame 101. -
Stoppers 157 are provided to themain body frame 101 respectively in vicinities of theinker frame 151. Each of thestoppers 157 is formed of an actuator, which detachably engages with theinker frame 151, and the like. In other words, theinker frame 151 is prevented from moving by thestoppers 157 engaging with theinker frame 151 when fitted into themain body frame 101. Disengaging thestoppers 157 from theinker frame 151 allows theinker frame 151 to move. - It should be noted that, in this embodiment, the
main body frame 101, theinker frame 151, thewheels 152, thebrackets 153, theguide rails 154, theguide members 155, thehandle 156, thestoppers 157 and the like constitute supporting means. - Descriptions will be given next of the operation of the intaglio printing press according to the embodiment described above.
- The
sheet 1 is firstly fed one by one onto the feeding table 21 from the top of thepile board 11 of thefeeder 10, and is transferred to thetransfer cylinder 31 of thegravure printing device 30 by the swingarm shaft pregripper 22. Thesheet 1 is then transferred from thetransfer cylinder 31 to thefirst impression cylinder 32, so that gravure printing is performed on a first surface of thesheet 1 with ink supplied from thefirst inking device 34 to thefirst intaglio cylinder 33 . After the ink thus formed on the first surface by the gravure printing is dried by thedryer 71A, thesheet 1 is transferred to thesecond intaglio cylinder 36 via thetransfer cylinder 35, so that the gravure printing is further performed on the first surface with ink supplied from thesecond inking device 38 to thesecond intaglio cylinder 37. After that, the ink further formed on the first surface by the gravure printing is dried by thedryer 71B, and thesheet 1 is transferred to thetransfer cylinders surface switching device 40 to be transported. - When both-side printing is performed on the
sheet 1, thesheet 1 transported from thetransfer cylinders suction cylinder 43 to theconvertible cylinder 44 to change the gripper thereof while the first and second surfaces of thesheet 1 are turned over. Thesheet 1 is consequently transferred to thetransfer cylinder 51 of the intaglio printing device 50 (refer to Japanese Examined Patent Publication No.Hei 6-041202 2005-088450 - Specifically, as shown in
Fig. 2A , the phases of thesuction cylinder 43 and the like are adjusted with respect to the phase of theconvertible cylinder 44 so that thesuction head 43b of thesuction cylinder 43 meets thesecond gripper device 44b of theconvertible cylinder 44. Thesheet 1 having printed on the first surface thereof is transported in a state where the forward edge portion of thesheet 1 is gripped by thegripper device 43a of thesuction cylinder 43 while the back edge portion thereof is sucked and held by thesuction head 43b. Then, the opening and closing of thesecond gripper device 44b of theconvertible cylinder 44 and the releasing of the suction of thesuction head 43b of thesuction cylinder 43 cause the back edge portion of thesheet 1 to be passed to, and thus be gripped by, thesecond gripper device 44b of theconvertible cylinder 44. At the same time, the opening and closing of thegripper device 43a of thesuction cylinder 43 cause the forward edge portion of thesheet 1 to be released. Accordingly, thesheet 1 is transferred to theconvertible cylinder 44 in a manner that the back edge portion of thesheet 1 precedes the forward edge portion thereof. Subsequently, the corresponding first andsecond gripper devices convertible cylinder 44 open and close at timings slightly different from each other, so that thesheet 1 is passed from thesecond gripper device 44b to thefirst gripper device 44a to be gripped by thefirst gripper device 44a. As a result, the first and second surfaces of thesheet 1 are turned over, so that the printing surfaces are switched. - The
sheet 1 having the printed surface switched as described above is transferred from thetransfer cylinder 51 to theimpression cylinder 52. Then, the intaglio printing is performed on the second surface of thesheet 1 with ink supplied to theintaglio cylinder 53 from theinking devices 56a to 56c via thepattern rollers 55a to 55c and theink collecting cylinder 54 as well as with ink supplied to theintaglio cylinder 53 from theinking device 56d via thepattern roller 55d. Thereafter, thesheet 1 is transferred to the take-off cylinder of thedelivery device 60, and is then gripped by the gripper bar. Then, while thesheet 1 is transported by thechain 63 traveling in association with the rotations of thesprockets dryer 72, and thesheet 1 is consequently delivered onto thepile board 64. - On the other hand, when one-side printing is performed on the
sheet 1, thesheet 1 transported from thetransfer cylinders suction cylinder 43 to theconvertible cylinder 44 to be gripped while the first and second surfaces of thesheet 1 are not turned over. Then, thesheet 1 is transferred to thetransfer cylinder 51 of theintaglio printing device 50. - Specifically, as shown in
Fig. 2B , the phases of thesuction cylinder 43 and the like are adjusted with respect to the phase of theconvertible cylinder 44 so that thegripper device 43a of thesuction cylinder 43 meets thefirst gripper device 44a of theconvertible cylinder 44. Thesheet 1 having printed on the first surface thereof is transported while the forward edge portion of thesheet 1 is gripped by thegripper device 43a of thesuction cylinder 43. The opening and closing of thefirst gripper device 44a of theconvertible cylinder 44, and the opening and closing of thegripper device 43a of thesuction cylinder 43 cause the forward edge portion to be passed to, and then gripped by thefirst gripper device 44a. Accordingly, thesheet 1 is transferred to theconvertible cylinder 44 in a manner that the forward edge portion precedes the back edge portion as it is. As a result, thesheet 1 is transported as it is without the switching of the printing surface. - After that, the
sheet 1 is transferred from thetransfer cylinder 51 to theimpression cylinder 52. Then, the intaglio printing is performed on the first surface of thesheet 1 with ink supplied to theintaglio cylinder 53 from theinking devices 56a to 56c via thepattern rollers 55a to 55c and theink collecting cylinder 54 as well as with ink supplied to theintaglio cylinder 53 from theinking device 56d via thepattern roller 55d. Thereafter, thesheet 1 is transferred to the take-off cylinder of thedelivery device 60, and is then gripped by the gripper bar. Then, while thesheet 1 is transported by thechain 63 traveling in association with the rotations of thesprockets dryer 72, and thesheet 1 is consequently delivered onto thepile board 64. - As described above, the intaglio printing press according to this embodiment makes it possible to perform gravure printing on one surface of the
sheet 1 while performing intaglio printing on the other surface of the sheet, in a single pass of thesheet 1. In other words, it is possible to perform intaglio printing on both surfaces of thesheet 1 at once. In addition, it is also possible to perform gravure printing and intaglio printing on one surface of thesheet 1 in a single pass. In other words, it is possible to perform intaglio printing on one surface of the sheet 1 a plurality of times at once. - The oscillating roller 56ac (56bc to 56dc) of the
inking device 56a (56b to 56d) of theintaglio printing device 50 is arranged in a manner that the outer peripheral surface of the oscillating roller 56ac (56bc to 56dc) is located vertically below the position of the gap between the edge of the bottom plate of the ink fountain 56aa (56ba to 56da) and the ink fountain roller 56ab (56bb to 56db), that is, vertically below the position of the edge portion of the ink fountain 56aa (56ba to 56da). Accordingly, ink dropped off the gap is received by the outer peripheral surface of the oscillating roller 56ac (56bc to 56dc), and is thus applied to the outer peripheral surface of the ink fountain roller 56ab (56bb to 56db). This makes it possible to suppress the smearing of the lower side of theinking device 56a (56b to 56d), and to greatly reduce the time and effort on the maintenance and the like. - In addition, it is possible to move the
inker frame 151 in a manner that the movement of theinker frame 151 is guided with theguide rails 154 and theguide members 155 while theinker frame 151 is movably supported on thefloor 100 with thewheels 152 and thebrackets 153 in between. Accordingly, it is possible to easily remove thepattern roller 55d and theinking device 56d with heavy loads out of themain body frame 101 by pulling theinker frame 151 from themain body frame 101. This allows the maintenance of thepattern roller 55d and theinking device 56d to be easily performed. - Moreover, the
inker frame 151 is movably supported on themain body frame 101 with theguide rails 154 and theguide members 155 in between without being in contact with thefloor 100. Accordingly, it is possible to securely bring thepattern roller 55d into contact with theintaglio cylinder 53 at a predetermined position at any time with accuracy, even in a case where thefloor 100 has a step, where thewheels 152 are abraded, or where there is an object between thefloor 100 and any one of thewheels 152. This makes it possible to securely prevent misprinting from occurring. - In the above-described first embodiment, the intaglio printing press configured as follows has been described. Specifically, in the intaglio printing press, the
intaglio printing device 50, which is provided with theinking device 56d and thepattern roller 55d in direct contact with theintaglio cylinder 53, and which communicates with theconvertible cylinder 44 of the printingsurface switching device 40 with thetransfer cylinder 51 in between is employed as the second intaglio printing unit. In addition, in the intaglio printing press, thetransfer cylinder 42, in a vicinity of which thedryer 71C is arranged, is positioned between thetransfer cylinder 41 and thesuction cylinder 43 of the printingsurface switching device 40. However, an intaglio printing press having the following configuration as shown inFig. 6 is also possible as a second embodiment. Specifically, theintaglio printing device 50, in which theinking device 56d and thepattern roller 55d in direct contact with theintaglio cylinder 53, are omitted, is employed as the second intaglio printing unit. In addition, thetransfer cylinder 42 and thedryer 71C are omitted, so that thetransfer cylinder 41 and thesuction cylinder 43 of the printingsurface switching device 40 are brought into direct contact with each other. Moreover, thetransfer cylinder 51 of theintaglio printing device 50 is omitted, so that theimpression cylinder 52 and theconvertible cylinder 44 of the printingsurface switching device 40 are brought into direct contact with each other. - In the above-described second embodiment, the intaglio printing press configured as follows has been described. Specifically, in the intaglio printing press, the
gravure printing device 30 provided with a plurality of theimpression cylinders intaglio cylinders inking devices doctor intaglio printing device 50, in which ink is supplied to theintaglio cylinder 53 from thepattern rollers 55a to 55c via theink collecting cylinder 54, is employed as the second intaglio printing unit. Moreover, thetransfer cylinders second impression cylinder 36 of thegravure printing device 30 and thesuction cylinder 43 of the printingsurface switching device 40. However, for example, an intaglio printing press having the following configuration as shown inFig. 7 is also possible as a third embodiment. Specifically, theintaglio printing device 50, in which theink collecting cylinder 54 and theform rollers 57a to 57c are omitted, and in which ink is thus supplied directly to theintaglio cylinder 53 from thepattern rollers 55a to 55c, is employed as the first intaglio printing unit. In addition, thegravure printing device 30, in which thesecond members transfer cylinders first members impression cylinder 52 of theintaglio printing device 50 is configured to communicate to thesuction cylinder 43 of the printingsurface switching device 40 with the take-off cylinder of thedelivery device 60, thesprockets chain 63, a take-off cylinder (not shown) having a configuration similar to the gripper bar or the like, thesprockets chain 47, the gripper bar (not shown) and the like, instead of thetransfer cylinder 41. Fourth Embodiment - Moreover, in the above-described first and second embodiments, descriptions have been given of the case where different kinds of intaglio printing methods are combined with each other. However, for example, as a fourth embodiment, it is also possible to employ the
gravure printing device 30 as an intaglio printing press which employs both of the first intaglio printing unit and the second intaglio printing unit, as shown inFig. 8 . Incidentally,reference numeral 65 inFig. 8 denotes a transfer cylinder. Other Embodiments - In the above-described first embodiment, the
